Web2py: pass parameters to db Connection()

问题

In web2py, in gluon/contrib/pymysql/connections.py there is a function that creates a new mySQL connection:

def __init__(self, host="localhost", user=None, passwd="",
             db=None, port=3306, unix_socket=None,

Is there any way to pass parameters to this function from web2py?

回答1:

As noted at the very end of this section of the documentation, you can specify a dictionary of driver_args when instantiating DAL:

db = DAL(<connection_string>,
         driver_args=dict(host='localhost', port=3306, ...))
